Applieation filed June 30, 1902. Serial No. 113,877. (No model.) I i Toall whom, it may concern:

Be it known that I, JOHN SCOTT, a citizen of the United States, residingat San Francisco, in the county of San Francisco and State ofCalifornia, have invented-certain new and useful Improvements inLever-Operated Vehicles, of which the following is a specification.

My invention relates to improvements in lever-propelled vehicles, theobject of my intion, combination, and arrangement of partsfor the aboveends,hereinafter fully specified, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 isa longitudinal vertical sectionof the apparatus. Fig. 2 is a plan view of the same, the seats beingremoved. ,Fig. 3 is an enlarged perspective view of one of the compoundlevers in one position. Fig. 4 is a similar view of a portion of thelever in another position. Fig. 5 is a horizontal section through thebearing of the rear axle. Fig. 6 is a detail of one of theratchet-wheels.

Referring to the drawings, the frame of the vehicle comprises the sidebars 1, the front cross-bar 2, the rear cross-bar 3, and the centralarched-bar 4.

5 and 6 are the front and rear seats, the former supported upon thecentral arched bar 4 and the latter upon springs 7, supported by theside bars.

8 represents the front axle, upon which the front portion of the framerests revolu'bly, said front axle being turned by means of thesteering-handles 9 and the steering-post 10, attached to said front axleand connected by means of a'bearing 11, loose upon the lower portion ofthe central arched bar 4.

12 represents the operating-levers, which are fulcru med upon the'bar 3,as shown at 13, and extend forwardly therefrom to the treadles 14 forthe front rider and are then bent backward upon themselves to thetreadles 15 for the rear rider. To said levers is attached a It isespecially adapted for chain or cord 16, which is passed over a smallroller 17, secured upon the under side of the arched bar 4. The efiectof this construction is that when either of the levers is depressed bypressure upon the treadle the other lever is correspondingly raised.Each lever has formed integral therewith an upstandingarm 18, which isconnected, as shown at 19, with a bar 20, the latter being pivoted atits upper endyas shown at 21, to an arm 22, swinging from a pivot 23upon the central arched bar 4. Thus the downward pressure of the lever12 causes theupper end of the arm 18 to swing forward, thereby vibratingforward also the lower end of the bar. 20. Each of said bars 20 isextended downward below its connection 19 with the arm, and to the lowerends of said bars are pivotally attached, as shown at 24, the upper endsof bent arms 25, the lower members of which are connected to crank-arms26, loose'upon a counter-shaft 27, extending across between the sidemembers 1 of the frame and having its endsin bearings 28 on said sidebars. Each crank carries a spring-actuated dog 29, which engages with aratchet-wheel;30,:fastened upon said shaft. Upon said shaft is secured asprocket-wheel 31,which is connected, by means ofasprocketchain 32, witha sprocket-pinion 33 upon the rear axle 34, said rear axle rotating inbearings 35, carried on the ends of the side members 1. 1

- -The operation of the device is therefore as follows: Upon depressingthe left-hand lever ,by means of the treadles the lower end of the bar20 swings forward, so that the upper end of the loose crank 26 alsoswings forward, causing the dog 29 to engage a tooth of theratchet-wheel 30 and propel the shaft forward. This rotary movement istransmitted to the rear axle at an increased velocity. In the meantimethe lever on the right was ascending and the arm 18 thereof swingingrearwardly, thereby moving the lower end of the corresponding bar 20 andalso the corresponding crank-arm 26rearwardly, causing the dog 29 toslip over the teeth of the ratchet-wheel to assume a new position for aforward movement.

In each bearing 28 the rear axle revolves on balls 36, and smaller balls37, between collars 38 upon said shaft, and cup-shaped nuts 39,

screwed within said bearing, prevent sidewise movement of thewheel-axle.

I claim-- 1. In combination with the frame, the arms 5 pivoted thereto,the bars pivotally connected 20 connected to said links and engagingsaid ratchet-wheels, the wheel-axle and the operative connection betweensaid axle and said shaft, substantially as described.

3. In combination with the frame, thearms pivoted thereto, the barspivotally connected with said arms, the treadle-levers pivot-allymounted upon the frame having the front treadles at their forward endand bent back and having the rear treadles at the ends of theirrearwardly-bent portions, and having arms pivotally connected with saidbars, the links connected to the lower ends of said bars, the shaft, theratchet-wheels thereon, and the dogs connected to said links andengaging said ratchet-wheels, substantially as described.

In witness whereof I have hereunto subscribed my name this 9th day ofJune, A. D. 1902.
